shown): of a common constructiolnon the projectiomtable of which is placed a: sketclil paper 3, 3Q SZiinches insidefthe* margin-,"9 which is `also i cross#hatched` into xsixteein, squares by lines 4.( Since thev camena en? largement is. eight times, the crossdiatchingf on the! design andl-` sketch paperf coincide: The sketch papen can benovediabout,` `toaolofv 9 tainlthe best focus, still keeping the lines rim coordination, and the designi may; be trains;` ferred by trac-ing Withfa, lead pencil. The

\ sketch paperis thenvplaced upont avmetaly screenf which` may contain' one hundred@1 forty-four holes to the square'inch of .O5 inch in diameter, and is held smoothly in place by vacuum or other suitable means. A screen (not shown) of celluloid or other transparent material having holes punched therein in accordance with thel series of punchings desired, is now placed on the sketch and the paper perforated by a series of hand-tools constructed with punches of said series, the punches made in the sketch paper alining with the perforations in the screen. Said Celluloid screen may be of small area,as 8 X 8 inches, or it may cover the entire sketch. To expedite this punching the hand-tools may consist of four tools that are one-quarter inch, one-half inch, one inch, and two inches square, with the punch points7 arranged in the desired series as indicated in Figs. 21, 22 and 23. Thus, for large block work two square inches'of paper may be punched out with one action. Surfaces smaller than one-quarter inch may be punched with single pointed tools.

Where the design is made ofsevera-l different colors, a separate sketch paper is punched for each color. Also, in case the design is of large area,such as eighty square inches, the enlarged design on the sketch ,paper afterbeing traced, is divided into a plurality of parts so that eachpart of the design appears on separate sheets.

After the design or.V parts of the design have thusrb'een punched out,-a second metal screen` 8` provided with perforations arranged the same as the first, is placed over each punched out sketch paper, and each sketch .paper together with the screens are placed in the head motion of the design transferringl machine.

During the operation of the machine, where five sketches, or patterns are employed, as above described, there will be five groups of punchings on each jacquard card, each group being transposed from the punchings ineach sketch. and the severaly groups being arranged side by side.

Previously to placing each sketch paper and its screens 6 and 8 in the head motion of the transferring machine, they are set into a skeleton frame 10 (Figs. 10 and 11) and securely held-in place by an outer frame member 12 detachably secured to the .frame by screws 14. The back of the frame is closed by a cover plate 16 spaced a distance back of the inner screen 6, and the screens are braced by vertical strips 18 having their rear edges secured to said cover plate and their forward edges bearing against the inner screen, the forward edge portions of theseV strips being sufficiently thin so as tol engage the inner screen between vertical rows kof perforations. Y

Eachdoublescreen, sketch and frame is mounted in vertical position in the machine, the several frames being spaced apart (Figs.

l, 2 and 3). The mounting for each frame comprises a grooved cross-bar 20 (Fig. 8) upon which the lower edge of the frame rests and is held, and grooved clamping members 22 (Fig. 4) which engage the upper edge of the frame adjacent its ends. These clamping members 22 are secured on downwardly spring pressed pins 24 which are pivotally mounted in bosses 26 on a cross-bar 28 so as to permit said members to be pulledV upwardly against the tension of their springs and swung out of the way to allow for insertion and removal of the screen frames. Each set of cross-bars 2O and 28 are secured at their ends to vertical rods 30.

Associated with each double screen and frame is a row of selecting needles 32 (Figs. 3 and 19) horizontally mounted in a channel iron support 34 secured to the machine frame. These needles are individually pressed toward the screen by a spring 36 coiled about the needle and engaging a collar 38 secured on the needle, the advancing movement of the needle being limited by a collar 39 secured on the outer end thereof and engaging the support 34.

Each selecting needle 82 of yeach row controls a griff wire 40, and the several griff wires associated with each row of selecting needles 32 has associated therewith a griff1 bar 42. The first three griff bars 42, viewlng Fig. 2, are carried by a common griff frame 44 and the other two griff bars are carried by a common frame 46. The griff frames 44 and 46 are respectively secured on the upper ends of vertical rods 48 mounted to slide in suitable bearings in the machine frame. y

The griff wires 40 individually control a bank of punches 50 (Figs. 14, 15 and 19) in the base of the machine. The connection between each griff wire and its punch 50 comprises a string v52 which has one end connected to the griff wire and its other end connected to a vertical finding pin 54. The strings 52 connected with all the griff wires pass through perforations in a collector plate 56 which is suitably supported on the frame of the machine, this collector plate guiding the strings vertically to the finding pins 54. Each finding pin 54 has associated therewith, an interferingpin 58 horizontally arranged and pressed toward the lower end portion of the finding pin by a spring GO coiled about the interfering pin and interposed between a collar 62 secured thereon and a re-setting plate 64 through which all of the interfering pins extend, stop collars 65 on the interfering pins abutting against the back of said re-setting plate. The outer end of cach interfering pin 58 is adapted to be positioned adjacent the upper end of each punch rod 50 so as to provide a stop for the rod. The several punch rods 50 are mounted to slide through apertures in a i plate 661 secured to the *machine trame, and also ink apertures in a `block 68, the

downward movement of the punches being limited-by collars `70:` secured" thereon` engaging the top sideof` the fixed guide plate 66;

The block 68de1 mounted: lon depending `pins 721` secured to the, plate 66,and^ the block is pressed downwardly `by springs coiled about the pins 72 andinterposed between the plate and" the block `68,downward movement of the block being `limited ley a flange 74 on the lowenend of each! pin 72.`

The chain ofjacquard` card blanks 75 to mounted: between. the endsof side frames 781, andtheupper stretch of the card chain eX- i tendingbetween, the cylinders rides overl a supporting` table 79 and a reciprocating punch blockBOfwhich is provided with aper` turesi82 for receiving the4 lowerends ofthe punches and-1 `through which the waste punchings from the jacquard cards are discharged.` v

Itwvill be apparentfthat` when a selecting needle 32:,is pushed back when no perfora tion` appears in" the slretchpaper, the upper hookedfend of the"V w-i-eAO associated therewith is positioned over' the associated griff board/l2 so "that upon the next upward l movement of" the griff, the griff wire is pulled upwardly and through the string 52 raises the" finding `pin liconnected tliere-` i with out of engagementwith the associated f am, interfering pint-8, allowing the springfof` the interfering pin to carrythe outer end thereofl out of interfering n engagement w ith the associated* punch rod 50. In case a selecting needle 32; enters a perforationin the .sketch paper4 the hooked end of the griff" wire 40"remains out of'position to be engaged bythe griff and, therefore, the associatedM interferingpin 581` remains in interfering l engagement with its associated punch rod.`

Then the punchnblock Sois raisedv to punch pushedz'upwardly by the card'. As the Y H, punched*blockSOfretraCtsfthe hlockw serves to strip `the punched' cardfrom` thepunches.

As` above indicated in the construction shown, each` horizontal linel of perforations ineach double screen consists of threehun dred` and; eightyfour` perforations; Each row` of` selecting` needles`32, however, may

have but ninetyfsix` needles,` and ,these nee-y` dles areequally spaceduap'art,` Consequently7 when the inachineis ready` to ,start operating number-s1, 2,3;4, and 5y, etc.,V needlesline t up, with 1j, 5 9,13Land1`17", etc., `perforations in, thevffirst horizontal line of'` perforations insthe screensA After the first line ofl perfo-` rations inthe screenhas thusloeen presented tothe selecting@ needles and thesereen is retracted, the screen is raised'to present the beperforated pass over card cylinders 76:

a card, the punches `thatare held by the l interfering pins" 578 serve to perforate the card, while the other punches are freeto he next horizontal line` of perforations to` the. selecting; needles, and the chain of` cards is adivancedl to `present the secondfcards of the pack to the bank of punches. In. similar.` mannen the remaining `horizontal lines `ofi perforations `in the screen `are presented toi the selecting needlesyand thecards successively punched; Atthe completion of this operation whereby each screen frameis intermittently raised to successively present the severalf'horizontall lines of perforations to the selecting needles, eachscreen frame isshilfted sidewise a distance corresponding tothe distance between the centers of cent `perforations inthe screen `so as to present the second, sixth, tenth, fourteenth, and

eighteenth, etc., perforations in the lowermost horizontal line of perforationsto the selectingfneedles. Also, the upper stretch ofthe chain ofcards is shifted'longitudinalu lyso as to present to the punches different points on the first card to be subsequently punched which is the last card that had been punched in the previous cycle of operation. When these adjustments 'have been made,

the machine is again thrown into operation` soas to cause each screen frame to be moved toward and from the selecting needles so i as to cause the perforations appearingin aflinementwith the lowermostlineof perforations in the `associated screen to he transposed tothe iirst card to again be punched. Eachdouble screenis then lowered-so as to present `the second'lowermostline of perforations to the selecting needles and` the chain ofcards is moved in a reverse directiontof its movement duringfthe first cycle ofoperation of the machine, topresent the next cardto theypunchesflln a similarfmanner the remaining Yhorizontal lines "of `perforations in each. screen are successivelyV presentedtothe selecting needles andthe cards 'intermittently fed to cause them to be punched. t

When all of the cards have again been punched during-'the lowering of the screens,

each screen frame is `then shifted edgewiseto lecting needles so as tocontrol the punches to perforate the first card in its new position.` The screen is their raised `intermittentlyi to successively present the remaining lines of perforations to the selecting needles, and the vcards are intermittently fed so as to he successivelypunched `as ahovedescribed;

the completion ofthis cycle of operation, the screens are shifted edgewiseto* successively les lill) las leo

aline the perforations 4, 8, 12, 16, 20, etc., in the lowermost line in the several screens with the associated selecting needles, and the upper stretch of the cards is shifted to the proper position to present different points to the punches. The several screens are then intermittently lowered to successively present the horizontal lines of perforatons to the selecting needles and the cards are fed in the opposite direction to successively present them to the punches.

Then these operations have been completed it will be apparent that'all the cards have Vbeen punched in accordance with the perforations in the sketch papers, and that the completely7 punched chain of cards is ready for use in a Jacquard loom, engraving, or similar' machine. Y

In the illustrated construction each bank or group of selecting` needles, consisting of ninety-six needles, is connected with a bank of punches, each bank consisting,` of ninetysix punches. The punches in each bank are arranged in'rows of six extending lengthwise and rows of sixteen extending crosswise of the upper stretch of the card chain. The five banks of punches associated with the five sets of screens are arranged side by side. The first six selecting needles of each group are respectively connectedwith the punches of the first lengthwise row of the associated bank of punches, and the next six needles are connected with the punches of the next such row of the bank and so on as indicated diagrainmatically in Fig. 19. Vith this arrangement of punches, when the machine is operated as above described with al-l five screen frames in operation, each card of the cardv chain may be perforated with the perforations appearing `in groups arranged side by side, eachgroup of perforations being transposed from the sketch of the associated screen frame. v

yFrom the foregoing it will be apparent, in accordance vwith my improvedY method and'machine that in case the design is of a single color and is approximately four inches square for example, it is only necessary to utilize but one screen frame and sketch. the design is of more than one color a separate frame and sketch would be employed for each color, the machine illustrated in the drawings being capable of at least live color work. Also, in case the design is of large area such as eighty square inches there is a screen frame for each division, the design being divided up into a plurality of parts as above described.

It will be apparent that the illustrated machine is a marked improvement over the usual piano-key card cutting machine which requires skilled operators, and is difficult laborious work to operate and is very exacting for the reason that if a mistake is made in making a single punch the card is spoiled. Also, with the use of my improved machine the several colors in a design are so transposed as to ensure proper matching of the colors when the cards are used in Jacquard looms and other machines. Also, where the machine is usedto perforate cards for a large design, such as eighty square inches, proper matching up of the different parts of the design is assured.

In the illustrated machine, the two griff frames 44 and 46 are raised and lowered to lift the griff wires through connection with a crank disk 82, Fig. The connection between the several griifs and the crank disk 82 comprises toggles 84, there being a toggle associated with both rods 48 of each griff. The upper arm of each toggle has its upper end pivotally connected at 86 with the griff rod 48 and the lower arm has its lower end pivotally connected at 88 on a fixed part of the machine frame. The inner ends of the arms of both the front and rear toggles are respectively connected by an actuating rod 90. Each rod 90 is operated by an oscillating arm 92 having vits free end pivotally connected with the rod 90 and its other end secured on a rock shaft 94. This rock shaft 94 is actuated through an arm 96 secured on the rear end thereof, and the free end of this arm is connected by a link 98 with the crank disk 82. l

The vertical rods 30 for supporting each screen frame are each mounted to slide in bearings on the ends of a carrier yoke 100. The series of yokes 100 on the front and rear of the machine are respectively secured on square rods 102 which have their ends mounted to slide in bearings in brackets 104 on slides 106 (Figs. 2 and 5) which are mounted on suitable supports on the machine. Y

The screen frames are raised and lowered to aline different lines of perforations with the selecting needles as above described, by pinions 108 (Figs. 3 and 8) which operatively engage rack teeth on the vertical carrier rods 30. rlhe two series of pinions 108 associated with the front and rear rack rods 30 are respectively carried byv horizontal shafts 110 which are journaled in` bearings 112 on the carrier yokes 100. The right hand ends of these pinion shafts 110 (Fig. 5) are driven through beveled gears 114 by a transverse shaft 116 journaled in bearings in bracket arms. 118 projecting from the right endmost carrier yoke 100. This shaft 116 is driven throughbeveled gears 120 by a shaft 122 journaled in bearings on the rear side of the machine frame. The beveled gear 120 on the shaft 116 is splined on the shaft and is maintained in operative engagement with the other beveled gear 120 by a spring 124 coiled about the shaft. This other beveled gearl 120 is splined on the shaft 122 and is held from retracting movedriven lshaft 146 I(Figs. 16 and 18).V As it is also through this shaft 146 that the screen frames are raised and lowered, it will be vapparent that the cards are successively presented tothe punches in proper timed relationto the operation of the screens, and that upon reversal of movement ofthe screens thei feeding movement of the cards will be correspondingly reversed.

The front and rear side frames 78 which kcarry the card cylinders, are mounted to shifted longitudinally to shift the upper stretch of the chain of cards through connection With the hand-operable shaft 220 through which the screens are shifted edgewise as above described,so that the adjust- -ment of the card to presentvdiiferent points thereon to the punches at the completion of each intermittent movement of the cards in one direction, and the edgewise shifting of the screen frames is accomplished simultaneously and correspondingly. The connection between'the side frames 78 andthe hand-wheel shaft 220 comprises screws 234 which extend through bearings in brackets 219 secured on the machine frame and are screw-threaded into bosses 221011 the side frames78, each `screw 234 being held from axial movement by collars secured thereon at opposite sides of the bracket 234. Each screw 234is connected by beveled gears 236 with avertical shaft 238, the two shafts 238 being connected through beveled gears 240 with the ends of the hand-operable shaft 220 (Fig. 14).V v

The punch block 8O is mounted to slide vertically in suitably formed guideways 1242 .(Figs. 14, 15 and 18) on the left side of the base of thefframe of the machine.r This punch block 80 is raised ,andV lowered in proper timed relation' to the feeding of the cards, through a connecting rod'244 having One end pivotally mounted on an eccentric pivot pin 246 and its other end on the wrist pin of a crank 248 formed on the drive sha-ft The throw of the punch block 8O may be varied by adjusting the eccentric pin 246. As shownthe outer end of this eccentric pin has-a segmental gear disk 243 secured thereon, andthe pin is adapted to be heldin iixed'po'sitionbyY means of a bolt 245 which extends-through anarcuate slotin the segmentalfgear Vdisk 243. The eccentric -pin maybe conveniently turned to 'effect the desired adjustment by means of a suitable Wrench 247 having a pinion v249 thereon whichis adapted to mesh with kthe teeth of theseg-mental gear disk so that vupon turn- .ing the wrench the desired adjustment may be effected. l The illustrated machine is provided with devices for properly centering each card prior to the punching thereof. These devices comprise dowel pins 250 (Figs. 12 and 18) and pin receiving holes 251 in plates 253 dovetailed on the top of the punch block 80 adjacent its ends. These dowel pins are mounted to slide vertically in bearings on brackets 252 which are carried by the card cylinder supporting frames 78. The dowel pins .250 are moved downwardly vas the punch block 80 is raised, by means of levers 254 pivotally mounted on the bracket 252 Aand vhaving corresponding ends pivotally 'connected with the upper ends of the dowel pins and their other ends conneetedthrough pin and slot connections with 'bracket arms 256 secured to the punch block. The dowel pins 250 tend to be held in raised position by means of springs 258v coiled about the upper portions thereof. With this construction, as the punch block is raised, the levers 254 act to force the dowel pins downwardly, and before the card engages the vpunches the pins are caused to enter the holes 259 in the card and the holes 251 in the plates 253, the pins having tapering ends so as to center the" card. The centering holes 259 are the usual holes that receive the pins on `the card feed cylinders. As the `punch block and card are retracted, the dowel pins 25() are raised out of engagement with the card so as toV permit the chain of cards to again be fed. Asthe brackets 252 for supporting the dowel pins 25() are carried'by the'sul'iporting frames 78 for the card cylinders, the dowel pins are properly shifted when the card cylinders are shifted to shift the upper stretch ofthe chain ofk slide longitudinally in suitable bearings on themachine frame. These rods 260 are provided A`with gear teeth that are engaged by pinions 262 secured'on a transverse shaft 264. V4The shaft 264 is connected by arms 266 with the ends of rods 268 that are adapted to be operated by eccentrics 27() carried by the shaft 176. Through this mechanism, near the completion of the upward movement of the grifls, the re-setting plate 64 is moved to the right,viewing` Fig. 15,'so as
